To study mechanical behaviors of shear walls built with precast two-way hollow slabs, two shear walls with different details of hollow slabs were quasi-statically tested under low cyclic loading. The failure mode was analyzed, which vertical macro-cracks appeared on walls due to the details of hollow slabs. Brittle shear failure can be avoided in terms of the failure behaviors evolved from inte...

Materials and Methods. Materials. Protease-inhibitor cocktail tablets and sequencing grade trypsin were obtained from Roche. N-octyl-glucoside was from Calbiochem, and tissue culture reagents were from Life Technologies. Tetracyclin-free foetal bovine sera (FBS) was from Perbio, and other tissue culture reagents were from Biowhittaker. Precast 4–12% and 10% polyacrylamide Bis-Tris gels were obt...

Effective and detailed planning of large-scale, complex construction projects is of great importance to fulfilling project cost and time objectives. At Tsinghua University of China and The Hong Kong Polytechnic University, the four dimensional-computer aided design (4D construction operations simulation methodology have been researched for years respectively, resulting in innovative, in constru...

It is impractical and uneconomic to design a structure that remains elastic throughout severe ground motions. The main design philosophy is that minor structural damages are acceptable as long as the structure does not collapse. Hence, seismic base isolation of structures provides a better alternative in constructing seismic resistant structures. A fixed-base structure designed in accordance to...

In this paper, a new roofing system is introduced, which is constructued using the precast composite sandwich panels. This roofing sandwich panels system consists of three kinds of precast concrete sandwich panels including capital panels, beam or between columns panels, and slab or middle panels. The panels are composed of three layers; A high strength reinforced concrete top layer. A thick la...
